BARREL-TRUSSING MACHINE.

To all whom fit may concern.'

Be it known that we, THOMAS A. SULLI- VAN and JOSEPH A. YOUNG, citizens of the United States, residing in the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Barrel-Trussing Machines, of which the following is a specification.

Our invention is designed to simplify and cheapen themamifacture of barrels provided with wire bilge hoops. Heretofore it has been the custom to truss bilge and end truss rings on the barrel in one trussing machine, pass the barrel to the crozing and chamfering machine, then knock off the bilge truss rings, substitute wire bilge hoops, and truss the latter in a second trussing machine, after which the end truss rings were removed and replaced usually by wire and wooden hoops driven by hand.

By means of our improved construction of trussing machine we are enabled to dispense with the second trussing machine above referred to, together with the time and labor involved in its use, thereby simplifying manipulation and economy in cost of production,-the usual bilge rings being removed from the barrel body and the bilge wire hoops being substituted in lieu thereof prior to placing the barrel body in the trussing machine.

The invention consists in the construction and arrangement of parts hereinafter described and claimed specifically, a distinguishing feature being the use of pivotally mounted segmental bilge-hoop drivers arranged to yield radially with relation to the barrel over and in Contact with the bilge surface of which theytravel in such a manner as to maintain touch with the comparatively small diameter of wire of which such bilge hoops are usually made. An incidental feature consists in the employment of gravity dogs for holding the barrel until the centralizing parts have cleared the ends of the latter during the retractile movement of the trusser mechanism, as hereinafter set forth.

ln the accompanying drawings, Figure 1, is a side elevation of a trussing machine to which our improvements are applied; Fig. 2, is a central vertical sectional elevation of the right hand portion thereof; Fig. 3, is a plan of the machine; Fig. 4:, a transverse Specification of Letters Patent.

The trussing mechanism at either end of the apparatus is essentially the same, so that the description and lettering applies to duplicate parts except where Otherwise specied.

F represents the frame work on which the operative parts are mounted.

P is'the power shaft mounted on bearings f, f, at each end of the frame, and on a pillow block f', between which and the adj acent end of the frame, said power shaft carries the usual driving and clutch mechanism A, controlled manually by the hand lever a, and connections. lVorm pinions p, (see particularly Fig. 2) on the main shaft P, engage with worm gears B, On transverse shafts o, which are mounted in bearings f2, on the side members of the frame F. Vertical yokes b, are suspended upon the transverse shafts o, and afford end supports for upper and lower guide rods b2. These yokes b', are also rigidly attached to the outer ends of the guides G, formed with lateral eXtensions g, which are attached to the side members of the frame F. The guides G, support cam plungers c, carrying cam rollers 0, which rest in the grooves c2, of the cam C. Rigidly attached to the inner ends of the cam plungers c, are the cross heads D which are also connected with, and slide upon, the guide rods b2. These cross heads are also formed with side flanges el, which rest in horizontal grooves in Vbrackets f3, of the frame F, thereby relieving the guide rods b2, preventing torsional strain, and lateral play. The end truss ring drivers d', are situated upon and project centrally from the cross heads D.

The bilge hoop driving rings E, are supg ported on the cross heads D, by means of spacing sleeves e, and bolts e, each ring E having mounted upon it a series of radially arranged segment-al bilge hoop drivers H, hereinafter described more fully and which constitute a distinguishing feature of our invention,the bilge hoop driving rings'E being substituted for those heretofore used for driving the bilge truss ring. p

The barrel centralizing cross heads I, are mounted slidably upon the guide rods b2, and having rigidly attached to them cam rods z', z', journaled in bearings g', on the lateral eX- tensions g, of the guides G. The outer ends of the cam rods z', are provided with vertical shoes 2, against vwhich the wiper cams J act,-said wiper cams being mounted on the transverse shafts and being timed ahead of the cams C, so as to advance the centralizing cones 3, on the crossheads I, justprior to the advance of the driving-mechanism. These centralizing cross heads are lretracted by the Ibilge hoop drivingrings E whenthe latter is retracted by thecam U.

The retaining dogs R which hold the barrel temporarily during the retractile movement of the driving mechanism until the centralizing cones 3, clear the ends of the barrel, are mounted upon sleeves S slidable upon the guide rod b2. The sleeves S are formed with arms s, which embrace the rack bars T (rectangular in cross section),which are pivotally supported at their outer ends on posts t, rigidly attached to the guide rods b2. Springs t, attached to'said posts t, andV to the sleeve S tendL constantly to hold the latter in Contact with the cross head I. Teeth t2, on the under side of the rack bars T, engage with knife edges s', on the sleeve S, the weight of the said pivoted bars T tending to maintain such engagement. Wlhen the cross heads I, and bilge hoop driver rings E, are advanced, the bars T yield to permit a corresponding advance of the sleeves S, but they hold the sleeves S in their advanced positions during the retractile movements of said cross heads I and driver rings E, until rollers 5, on said cross heads I, encounter the inclined surfaces t, on the undersides of the bars T, thereby raising said bars sufficiently to release the sleeves S, and allow them to be returned by the springs t', to their normal positions, rest-k ing against the cross heads I.V This clogging mechanism has been used heretofore in connection with the bilge truss rings,-'the novelty in the present case in this connection, consisting in substituting yielding or gravity hoop drivers H, maybe arranged radially dogs", for the rigid dogs heretofore used to temporarily engage the bilge truss ,rings for the purpose above stated.

The dogs R as yused 'by us consist of seg-V ment-al concave bearings r, pivotally attached to yokes r, mounted slidably between flanges s2, on the under sides of the sleeves S. In the drawings the vertical play is shown as provided for above these Hanges s2, the pins s3, upon which the yokes r, are suspended projecting .above said flanges, as will be understood by reference to Figs. 16, Y 17 and 1S. By pivotally attaching the concave segmental bearings fr, 'to the radially yielding yokes r", said bearingsare free to adapt themselves to any inequality of bilge surface and still maintain contact with a hoop wire of small diameter. f

Any desired number of our bilge wire on each ring E. Each driver consists essentially of aV concave segmental shoe or bearing piece L, pivotally attached to a slide JL', which is resiliently mounted on the ring The object of pivotally attaching the bearing shoe 7L, to the slide L, is to enable itto adapt itself -to inequalities of surface owing to imperfect alinement of f staves, as illus'- tratcd diagrammatically inFig. 10. Thus` all danger of jumping or over-riding the wire hoop is obviated, and a continuous 'contact assured with the smallest :diameter of wire while the hoop is being driven over the bilge.

The object of supporting the bearingshoe 71 on a resiliently .mounted slide z-, is to enable the driver to yield radially with relation to the barrel as the wire hoop is driven over the bilge, so as vto afford a uniform support to the wire hoop from the beginning to the end of the operation of trussing. yThis is insured because contact is maintained, Y with the bilge surface, so that a hoop made of a very small diameter of `wire may be used.

At the same time the machine is adapted for thus trussing more than one size of barrel,

It is obvious thatva'rious mechanica'lexpedients may be resorted to in this respect withlike result, and we do not conine'ourselves strictly to the identical form and con` 115 struction of parts herein described, although the drawings show mechanism which has been actually and successfullyemployed byl usrin the manufacture of barrels provided with wire bilge hoops.'

As shown in thel drawings each concave bearing shoe IL is pivotally'secured to a U- shaped slide 7L', the parallel members of which rest in a box m, which is secured in ai recess'el, in the ring E, by means of a bind- 125 ing screw e3. 'This admits `of the boxes and drivers being `set and adjusted radiallyy with' relation to the 'sizes of the vbarrelsto which the wire hoops/w, are to be applied. i Inter` posed between? the Across member ofthe U- 130 shaped slide 7i, and the upper closed end m', of the boX m, is a coiled spring n., which tends constantly to thrust the slide inward toward the center of the ring E. This outward thrust is limited by set nuts 71.2, on the outer threaded end of a stud 71,3, projecting from the cross member of the U-shaped slide 72,', and through a hole m2, in the end m', of the box m. These set nuts 71,2, afford means of adjusting the thrust of the slide 7L, with accuracy. m3, is a. cover for one side of the box m.

In operation the barrel as set up with both end truss rings and bilge truss rings in place as in Fig. 5, is fired, and the bilge truss rings Q, are then removed and the wire bilge hoops w, substituted in lieu thereof as in Fig. 6, when the barrel is introduced into the machine and the wire hoop trussed simultaneously with the trussing of the end truss rings a. The ends of the barrel are then croied and chamfered in the usual manner, the end truss rings u, removed and hoops substituted as heretofore.

That we claim as our invention and desire to secure by Letters Patent is,
